Im convinced only 1% of the player base knows how to do Tera Raids

I I know there are already countless posts about this topic, and not to beat a dead horse or anything, but seriously, what is actually wrong with people? I was in a raid with three other people against a Fire Tera type Porygon-Z with my Garchomp, and my other teammates ran Quaquaval, Gyarados, and Skeledirge of all things. I did a single Swords Dance and then Earthquake and did almost a quarter of the Porygon's HP while my teammates were doing chip damage and getting one-shot. Did they realize Porygon-Z can learn Zap Cannon and Tri Attack? My Garchomp carried the weight, but we still lost because each of the other three players died two times each, or three in the Gyarados' case. Then another raid where someone brought a Scizor to a Volcarona... I don't even feel like I have to explain why that's a terrible idea. Both of these were six-star raids, so it's impossible they were all new players, right?

Countless other times where I join a raid and everyone focuses on the defensive Tera type and ignores the base type or vice versa, and also the fact that I'm pretty sure these people are digging into their back pocket for some trash IV level 65-70 that has mediocre movesets at best. FFS.
